A method of making 1-olefin such as 1-butene by contacting a mixed olefin feedstock preferably with a small pore molecular sieve catalyst, especially SAPO-34, at a temperature from about 300° C. to about 700° C., and an effective pressure and WHSV to form an olefin product with a 1-olefin:isoolefin conversion index greater than 1:1. A mixed olefin feedstock produced from an oxygenate to olefin process is particularly well suited for the production of 1-olefin.
通过将混合烯烃原料与小孔
分子筛催化剂(特别是
SAPO-34)接触,在温度约300°C至约700°C下,以及有效的压力和WHSV,制备1-
丁烯等1-烯烃的方法,形成1-烯烃:异构烯烃转化指数大于1:1的烯烃产品。从氧化物转化为烯烃过程产生的混合烯烃原料特别适用于1-烯烃的生产。
